Introduction
Compared with eating slowly, eating quickly generally increases the likelihood of weight gain. It may take approximately 20 minutes for satiety signals from the stomach to reach the brain. When eating rapidly, individuals often consume more food before feeling full, thereby increasing the risk of weight gain. In contrast, eating slowly allows individuals to promptly stop eating once satiety signals are perceived, helping to control portion size and reduce the risk of obesity.

Eating quickly generally makes one more prone to gaining weight compared to eating slowly.

Since it may take about 20 minutes for signals from the stomach's contents to be relayed back to the brain, eating too quickly can result in consuming excess food before the body senses fullness, making weight gain more likely. Additionally, consistently eating too fast over a long period may increase stomach capacity, leading to gastric dilation, which delays the onset of hunger. As a result, people may unknowingly consume larger amounts of food, further contributing to weight gain. Moreover, rapid eating can place extra strain on the digestive system and lead to indigestion. In contrast, eating slowly allows individuals to stop promptly once they feel full, helping control food intake and reducing the likelihood of obesity.

In addition, maintaining a pleasant mood and emotional stability during meals aids digestion and nutrient absorption. It is also beneficial to drink an appropriate amount of soup or fluids with meals, which supports overall health.
